Your organization runs a personal (persistent) host pool where each user is assigned a dedicated session host VM. Users store business-critical data directly on the OS disk and an attached data disk of each VM. Leadership requires that individual VMs can be fully restored to a specific point in time (including OS and data disks) within a 7-day retention window if a VM is corrupted or accidentally deleted. Which backup approach should you implement to meet this requirement with the least operational overhead?
